Claims priority, application Netherlands April 13, 1951 1 Claim.

The present invention relates to a hanging spinning or twisting pot and more particularly to the execution of the lubricating device thereof.

In lubricating the bearings of hanging spinning or twisting pots the supply of the lubricant, e. g. oil, is carried out in drops on the topside of the bearings, and means must obviously be present for collecting the used lubricant. This is in the present case very important because the spinning or twisting pot is in a hanging position and the spun or twisted material can be soiled by the lubricant rather easily. Also one must take care that the collecting means cannot be drained by the centrifugal action of the rotating spinning or twisting pot, for this would cause the lubricant to be removed in an undesirable manner.

In order to avoid the above cited problems the hanging spinning or twisting pot is designed according to the present invention.

The hanging spinning or twisting pot according to the invention comprises a tubelike driving shaft to the bottom of which the topside of the spinning or twisting pot is connected and which is rotatable in a casing by means of ball or roller bearings, and which is also provided with a device for lubricating the bearing in drops from the topside and with a collecting means having a drain for the used lubricant at the bottomside of the casing, the tubelike driving shaft being provided at the level of a slit formed between the bottomside of the collecting means and the topside of the pot, with one or more transversal bores.

In the drawing an embodiment of the spinning pot according to the invention is shown by way of example. The spinning pot is indicated by I. Said pot is at its topside connected to the flange-shaped bottomside 3 of the hollow shaft 4 by means of bolts 2, said bottomside also forming the top of the pot. Through said hollow shaft 4 the thread which is not indicated descends into the pot I and is pushed gradually against the inner wall of the pot by the quick rotation thereof. The shaft 4 is at its top end provided with a pulley 5 which is rotated by a belt or the like, which is not indicated. The shaft is rotatable in a casing 8 by means of two ball bearings 6 and l. The outer rings of the bearings 6 and l are pressed apart by means of a helical spring 9. The casing 8 is provided with a spherical surface ll! which rests in a hollow surface ll of the machine [2 so that the 2 casing 8 with its bearings 6 and l, the hollow shaft 4 end the pot I can oscillate somewhat and can adjust itself according to the axis of rotation. To limit the oscillation movement a rubber ring I3 is positioned between the casing l and the machine.

The bearings are lubricated by means of a drop lubricating means having a supply l4 at the top of the casing. At the bottomside of the casing a collecting device I5 is pltced for collecting the oil which drops from the bearings 6 and l. The extended edge It of the collecting means I5 is extended to the outer circumference of the shaft 4; however, there always will be a slit l'l. Under the bottom bearing 1 an annular-shaped guiding surface I8 is provided and is connected to the shaft 4 for bridging the slit H. The oil collected in the collecting means I5 is drained through a draining part l9.

Since there is also between the flange 3 at the bottomside of the shaft 4, when rotating, and the bottomside of the bottom 20 of the collecting means l5 which is fixed, a slit-shaped space H, a sucking action is exercised on the slit I! by the quick rotation of said flange 3; by this fact an oil mist or oil drops are sucked from the collecting means 15 and are hurled from the outer circumference of the flange 3. The material to be spun or twisted can easily be soiled by said oil. To avoid said disadvantage holes 22 are drilled in the wall of the hollow shaft 4. The centrifugal sucking action is then brought to bear only on the interior of the shaft 4 which is harmless and no sucking action is exercised on the slit H. A mantle 23 is arranged about the spinning pot I.

What is claimed is: Hanging spinning or twisting pot having a tube-shaped driving shaft to the bottom of which slit.
